As vaccine eligibility expanded Monday to 4.4 million Californians with health conditions that make them more vulnerable to COVID-19, Facebook announced a new feature Monday to help people figure out when and where they can get vaccinated.

The feature, which will appear in Facebook account-holders’ news feeds as well as on Instagram accounts, aims “to make it easier for everyone to get vaccinated,” Mark Zuckerberg, Facebook’s founder and CEO, said in a post Monday.
